Review: Good-bye fire ants..........! - It works really well. Kills the whole mound and the queen as advertised. I dug into the mounds afterwards to see how effective and no ants or movement. Helps me keep the yard safe for my mother who likes to garden. Poor woman was being bitten all the time and no longer wanted to care for her plants. This helped. Don't know how long it will last yet. We shall see. ....Edit 05/01/26...While it works well and kills the mound, I am not able to keep them from coming back. It's like playing wack-a-mole. Still, a good product.

I had fire ants all over my yard and after using Ortho Orthene Fire Ant Killer1, they were gone super fast. The smell is a little strong, but it does the job. I would definitely buy it again.

## Questions & Answers

**Q: Can Ortho Orthene Fire Ant Killer Broadcast Granules and Mound Treatment be used indoors?**
A: This product is for outdoor use only. Fire ants are best treated at the source—their mounds, which they typically build in lawns, fields, or pastures. If you're seeing ants indoors, you're probably dealing with a different type of ant.

**Q: What is the best time to apply fire ant killer?**
A: When ants are most active: in the early morning and late evening. Applying during these cooler times of day is better for you, too, since you won't be out during the hottest part of the day. Just make sure temperatures are between 65°F and 80°F.

**Q: Are Ortho Orthene Fire Ant Killer Broadcast Granules and Mound Treatment safe to use around my pets?**
A: The best way to keep your pets safe is to follow all label directions. That means not allowing people or pets to reenter treated areas until granules have been watered in and the area has dried.

### ⭐⭐⭐⭐⭐ Knocks out imported red "fire" ants
*by W***E on May 10, 2026*

I have used Orthene for years! It decimates a bed of fire ants in a few hours. Do not disturb the mound, apply it on the mound and around the perimeter about 6" to 10". It is a great contact killer. You can see them getting all "herky-jerky" once they are exposed to it. I recommend apply it using gloves and in calm conditions. It is a powder and will be harder to effectively place it if windy. The light dusting will get them coming out - then the countdown is on! I try and pound them after some rainfall and they are on the move. You won't kill 'em all, but you can get them moving outside of your property line. Good luck because they are vicious little guys!
